Littelfuse CCMR012.T Cc Time Delay Cartridge Fuse 12A

Product Description

The LITTELFUSE CCMR012.T is a Class CC time delay cartridge fuse rated at 12 amps for use in industrial and commercial electrical systems. It features a dual-element design that tolerates brief inrush currents without nuisance tripping while still providing reliable overcurrent protection under sustained fault conditions. The fuse measures 1.5 inches in overall length and 0.41 inches in diameter, fitting standard Class CC fuse holders. With an interrupting rating of 20 kA at DC and 200 amps RMS symmetrical, it is suited for branch circuit and equipment protection where time delay characteristics are required. Licensed electricians and qualified technicians are the typical installers.

Class CC fuses are widely used in motor control centers, industrial control panels, HVAC equipment, and other applications where inrush current from motors or transformers must be tolerated at startup. The CCMR012.T fits into standard Class CC fuse holders and rejection-type fuseholders, making it a straightforward field replacement in a broad range of control and power distribution equipment. Its compact cartridge form and dual-element construction make it appropriate for both new installations and service replacements in tight panel spaces.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. Always de-energize and lock out the circuit before replacing a fuse. Use an appropriately rated fuse puller when removing or inserting the fuse from the holder. Verify that the replacement fuse matches the amperage, class, and interrupting rating required by the equipment manufacturer before energizing the circuit.
